CPH
Box of Hybrid Protection

The protecting type CPH-X-VVV is projected for protection of equipments connected to nets of telecommunications, computer science or of sign for 1, equal 2 and 4, against sobretensões and transientes provoked by fall of rays or inductions of the net of energy.

The configuration of the protection is hybrid, with centelhadores tripolares to gas in the side of the external line and varistores or semiconductors (Tranzorb) on the side of the equipment, coordinated by two termistores or PTCs, guaranteeing simultâneamente great current capacity, low residual tension for the equipment and fast time of answer, tends as purpose to minimize it it burns of the equipments for him protected.

Code of the Product	Application
CPH-X-8	Computer science nets, industrial automation or sign lines with tension of work maxim of 6V.
CPH-X-15	Computer science nets, industrial automation or sign lines with tension of work maxim of 15V.
CP-X-30	Computer science nets, industrial automation or sign lines with tension of work maxim of 24V.
CPH-X-T	Phone net, without extending of connection. (PABX, modens, answering machines and etc.)
X	Number of lines (equal) = 1, 2 and 4
